But such is not the case in New South Wales.

There, no such accumulations of vegetable matter are to be met with; but where the loftiest tree of the forest falls to the ground, its figure and length are marked out by the total want of vegetation within a certain distance of it, and a small elevation of earth, resembling more the refuse or scoria of burnt bricks than any thing else, is all that ultimately remains of the immense body which time or accident had prostrated.

Thus it would appear, that it is not less to the character of its woods than to the ravages of fire that New South Wales owes its general sterility.
CONNECTION BETWEEN THE GEOLOGY AND VEGETATION.
Whilst prosecuting my researches in the interior of the colony, I could not but be struck with the apparent connection between its geology and vegetation; so strong, indeed, was this connection, that I had little difficulty, after a short experience, in judging of the rock that formed the basis of the country over which I was travelling, from the kind of tree or herbage that flourished in the soil above it.

The eucalyptus pulv., a species of eucalyptus having a glaucus-coloured leaf, of dwarfish habits and growing mostly in scrub, betrayed the sandstone formation, wherever it existed, This was the case in many parts of the County of Cumberland, in some parts of Wombat Brush, at the two passes on the great south road, over a great extent of country to the N.W.of Yass Plains, and at Blackheath on the summit of the Blue Mountains.

On the other hand, those open grassy and park-like tracts, of which so much has been said, characterise the secondary ranges of granite and porphyry.
